Alas several MUAs don't quote attachments in replies.  Hence the optimum
would be if you use a MUA which allows to insert text files without
whitespace change.

Also, when you respond on LKML, always use "reply to all" to keep
previous responders in a thread Cc'd.  This is necessary due to the high
volume of LKML, and in order to not force people to subscribe to LKML.

.done and .wait are not public AFAIU and should therefore not be
documented as an API.

The last sentence is redundant and should be omitted.
